Why is AutoMapper not mapping from NPoco dynamic object to entity?

Question

When I do an NPoco fetch

var products = db.Fetch<dynamic>(sql).ToArray();

and then try to map it with AutoMapper

Mapper.Map<Product[]>(loc)

The resulting Product does not have any of the expected values even though

• The names and case of the column names in sql, the NPoco.PocoExpando instances in products, and the Product class, and they all match.
• The values in the expando are correct for each column.
• The setters in Product are public.

The AutoMapper documentation suggests that I'm doing everything correctly. Is this a bug or am I missing something?

Answer 1

In my call to Mapper.Initialize I set IMapperConfigurationExpression.CreateMissingTypeMaps to true. It seems that doing this interferes with the dynamic mapping.
